AUTOMATIC GAS-VAPOR PRIMER.

- Specification of Letters Patent.

Patented Dec. 2, 1919.

Application filed February 14, 1919. Serial No. 276,978.

To all whom it may concern:

Be it known that I, CLARENCE P. WOOD, a citizen of the United States, residingin the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Automatic Gas-Vapor Primer, of Wh1ch the following is a specification; My invention consists of a devlce by which an automobile may be automatically primed with gas vapor, admitting of the use of a fuel of lower grade, the same being hereinafter described and the novel features thereof pointed out in the distinctive claims I that follow the specification.

The invention is satisfactorily illustrated in the-accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific details shown and described, as long as they are within the spirit or scope of the claims.

Figure 1 represents a vertical section of.

I a device embodying my invention on line the lower end thereof.

Connected with the head is the tube 4 the top of which is provided with the filling cap 5 in which is the vent 6, said tube 4 being in communication with the container by the passage 7 In the upper portion of the container is the flexible diaphragm 8 whose peripheral portion is clamped between the bottom of the head and the top of the container. In the bottom of the container is the port 9 the lower end of which forms the seat 10 for the ball-valve 11 whose stem 12 passes through said port 9 and from thence upwardly through the container to the diaphragm to the center of which latter it is firmly connected as at 13.

In the head 2 is the jet'or nozzle 14: in which is the needle valve 15 whose point is at the outlet 16 of said nozzle, the stem of said valve being threaded in the plug 17 in the head 2 and having an operating handle 18 on the exterior of said head. 19 designates an inlet which is closed except when it is required to be opened for testing the device.

On the upper end of said head is the inlet 20 for water, vapor and air. At the side of said head is the outlet 21 for the gas vapor. The interior of the head around the stem 15 forms a gas chamber 15 which is in communication with the interior of the nozzle 14. Leading from said chamber is the gas passage 22 which is connected with the gas feed pipe 23 which is located within the container 1 and has its lower end connected with the bottom of the container, the outer terminal of said passage being closed by the plug 22*.

24 designates a sleeve which is attached to the bottom of the container, the interior of said sleeve forming a reservoir 25 in which is fitted the screw plug 26 whereby the capacity of said reservoir may be adjusted, it being noticed that when the ball v'alvell is lowered it may enter said reservoir. 1

In the upper end of the sleeve 24 is the horizontally extending gas duct 27 which is in communication with the lower end of the gas feed pipe 23, said duct being also in communication with the upper end of the gas conveying groove 28- which extends vertically in the wall of the sleeve 24 and has its lower end in communication with the gas duct 29 in the inner side of the lower portion of said sleeve 24.

Within the container 1 is the vent pipe 30 whose lower end is connected with the bottom of said container and is in communication with the passage 31 in said bottom, said passage being in communication with the reservoir 25. The upper portion of said vent pipe passes through the wall of the container where it is continued upward as at 32 exterior of the latter and opens into the atmosphere.

It will be seen that the gasolene passes from the container through the ball valve 11 to the reservoir 25, thence into the grooves 27 and 26 and through the groove 28 into the feed pipe 23, and so reaches the chamber 15* when it enters the nozzle 14: and flows through the needle valve and escapes therefrom into the adjacent portion of the head 2 when it mixes with air admitted into said portion by the inlet 20, the resultant gas then entering the manifold by suction through the outlet 21.

The suction from the engine causes the operation of the diaphragm 8 whereby the ball valve 11 is closed, thus shutting oif the supply of gas excepting what remains in the reservoir 25 and the feed pipe 23, as a measured amount required for the starting prime.

Water may be admitted into the head through the inlet 20'for moistening the vapor and decarbonizing.

It will be seen also that the area of the chamber surrounding the nozzle 16 1s greater than the area of the inlet 20, consequently, the suction of the engine through outlet 21, which is connected directly to the intake manifold of engine above carbureter, causes .a vacuum in said chamber, which causes the gas to be sucked through nozzle 16, mixing with air from inlet 20, and entering the intake manifold as a rich gas vapor. At the same time, the same suction operates to draw up the sensitive diaphragm 8, which thus closes valve 11, thus preventing the flow of more gas to measuring chamber, Fig. 4:.

My primer is principally for the starting I of a car, it acts also as an accelerator after the car is started to rapidly change from one speed to another. It converts a gasolene engine into a kerosene engine without in any way affecting the engine construction, and without changing the adjustments from those which are used when operating with gasolene, nor does it in any way affect the carbureter already on the engine, nor change the vaporization of the kerosene used, in short, its function is to furnish instantaneously to the motor when needed a small prime of rich gas vapor, which gives an added impetus to the engine, when under ordinary conditions the sluggishness of the fuel used would have a tendency to flood the carbureter, and thus be not entirely consumed by the engine.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

1. In a device of the character stated, a container, a reservoir member in communication therewith, a gas chamber in the head of said container separate therefrom, a gas feed pipe in communication with said reservoir member, a valve in said head in communication with the gas chamber and the outlet of said head, a valve intermediate of said reservoir member and container, a flexible diaphragm in the container, and a connection between said diaphragm andthe latter named valve.

2. In a device of the.character stated, a container, a reservoir member in communication therewith, a gas chamber in the head of said container separate therefrom, an air vent pipe in communication with said reservoir member, a gas feed pipe in communication with said reservoir member, a valve in said head in communication with the gas chamber and the outlet of said head, a valve intermediate of said reservoir member, and container, a flexible diaphragm in the container, and a connection between said diaphragm and the latter named valve.

3. In a device of the character stated, a container, a reservoir member, a port intermediate of said member and container, a valve for said port, a vent pipe, a gas feed pipe, said pipes being in communication with said reservoir member, and gas ducts in said reservoir member intermediate of said vent and gas feed pipes forming means of communication for the reservoir member.

4. A container, a reservoir member communicating therewith, a valve intermediate of said member and container, a flexible diaphragm in said container, a connection between said diaphragm and valve, a gas receiving chamber in the head of the container separated from said container, a feed pipe in communication with said reservoir memher and gas receiving chamber, a valve in the latter, and an outlet for the gas leading from said valve.

5.
